9 Claimsr... (o1. 139. 255) This invention relates *to improvements 'in resceivers for spent bobbins in" weftreplhl-shirlg looms and it is the general object of- 'the inven-= tion'to provide amounting for the receiver which can-be swung forwardly to permit removal crane holder for the spent'bobbins.

In weft replenishing looms it is common practice to provide a can orreceptacle'for tritede:v pleted bobbinswhichare expelled fromtheloomincident to weft replenishing operations? A-form' of receiver'for "such bobbins which has gone intouse employs a cloth bag suspended from -a;metal frame 'Which' in the-past has been supportedby' the loom. It'is an important object ofthe pres ent' invention to provide afloorsupportedmount ing forsuch a receiver including an upright piv oted'to swing forwardly from its-normal rear'rpm sition to permit upward removalof thereceiverrk It is a further object of'the inventionto-pro' vide a mounting for the receiver'having'a:pivoted upright part on which-is mounted'a vertically 'ad justable carrier for the bobbin receiver] so that" the latter-can be adjusted :to the correctipositio'n forreceiving the spent bobbins'asfthey. are dis Q as a spring which will permit forward'"'swlnging:;i of the mounting and receiver when. the latteritis to be removed.

3 51 to the top of the block 45 and has the opposite ends thereof hooked to form pockets 52 to receive the side members 20 and 2 I.

As shown more particularly in Fig. 5 the shoe 38 cooperates with lock means L to hold the rod 40 normally in the bobbin receiving position shown in Fig. 2. The shoe has a rounded nose 55 to receive the curved end 55 of a leaf spring 57 secured as at 58 to the base 30. The curved end 56 normally fits around the nose 55 and exerts a yielding force thereon tending to hold the shoe 38 and upright rod 40 in normal position such as shown for instance in Fig. 2, The spring 5! will yield when the shoe 38 is turned aroundthe pivotal connection 31 in a counterclockwise direction as viewed in Fig. 5. The shoe has a stop surface 59 which normally engages the base 30 to limit movement of the rod 40 rearwardly toward the lay, or to the right as viewed in Fig. 5.

When the receiver R and the mounting therefor are in the normal position shown in Fig. 2 and in full lines in Fig. 4 the rod 40 will be substantially vertical and the spring 57 by its engagement with the nose 55 will hold the receiver in its normal position with the mouth 21 located to receive bobbins which move downwardly along the chute 5. The side frame members 20 and 2! will be received by the pockets 52 and because of the fact that the members are inclined downwardly and toward each other the carrier 58 will support the receiver in a position determined by the vertical location of the block 45 along the rod 4! a When the bag 6 requires emptying because of an accumulation of depleted bobbins therein the operator will grasp cross bar 28 and swing the receiver and rod All forwardly from the full line to the abnormal dotted line position shown in Fig. 4, the spring 51 yielding upwardly slightly to permit this angular motion of the receiver. The bag 6 and frame are then removed by upward motion, the side members and 2| moving out of the pockets 52 incident to upward motion of the receiver and the cross bar sliding upwardly along rod 40.

The rod 40 will remain in the dotted line position shown in Fig. 4 due to its weight, but if desired the rounded part of the spring 55 may engage a surface 60 of the shoe 38 to exert a force to the left as viewed in Fig. 5 tending to hold the rod in its abnormal position. The under side of the shoe is provided with a stop surface 5! which will engage the top surface 52 of the base when the mounting has been moved to its abnormal position.

After the bag has been inverted to empty its contents into a truck or the like provided for the purpose the operator will return the bag to its holding position with respect to the carrier 50, sliding the lower forward end of the bag and frame 15 along the rod 40 and guiding the members 20 and 2| into the pockets 52. By means of the cross bar 28 the frame and bag are then moved back to their normal position from the dotted line to the full line position shown in Fig. 4, the bent end 56 and spring 51 reestablishine yielding holding relation with respect to the shoe 38 to maintain the latter and the receiver in normal position.

If it be desired to raise the frame l5 and bag 6 to locate the mouth 21 nearer the bobbin chute 5 the" set screw 46 can be loosened and block 45 slid upwardly along rod 40, after which the set screw can be tightened. A similar but more limited adjustment could be attained by slackening the set screw 4| and moving the lower end of the rod with respect to the shoe. While the carrier 50 has been shown in the form of a piece of fiat sheet metal the invention is not limited to this form of carr1er.

From Fig. 2 it will be apparent that the receiver R is behind the rod 40 and tends due to its weight to turn in a clockwise direction around the carrier 42 and move the cross bar 22 forwardly, or to the left. The rod 40, however, limits this motion and cooperates with the cross bar to hold the mouth 21 of the bag in correct bobbin receiving position.

From the foregoing it will be seen that the invention sets forth simple means for supporting the bag 6 and frame [5 in such manner that it can be swung forwardly and then readily removed by an upward motion to permit emptying the contents of the bag. When the receiver is returned to its normal position its lower end can slide down around the rod 40 as the side members 28 and 2l' are guided into the pockets 52. Vertical adjustment of the receiver can be effected by sliding the block 45 along the rod 40. The spring 51 normally overcomes any tendency of the receiver to move from the full line to the dotted line position indicated in Fig. 4, but the spring will yield to permit the receiver to be swung forwardly to its abnormal position from which it can be removed from its mounting. The under side of the shoe 3!; has stop surfaces to engage the base 30 to-limit angular motion of the rod 40 and receiver R, around pivot pin 31. If desired the shoe 38 can be provided with a, surface 60 to engage the spring 51 and enable the latter to assist gravity to hold the rod 4!! in its abnormal position. Also, the rod 48 limits forward motion of cross bar 22 and holds the mouth 21 in correct bobbin receiving position when the parts are in normal position. The set screw 45 permits the block 45 and the carrier 42 to be adjusted angularly in a horizontal direction around the upright rod 40 to permit the receptacle to be aligned with the lay without disturbing the base 30.

Having thus described the invention it will be seen that changes and modifications of the foregoing specific disclosure may be made without departing from the spirit and scope of the invention.

What is claimed as new is:

. i. In a weft replenishing loom provided with a receptacle for spent bobbins discharged from the loom lay incident to replenishing operations, a frame supporting the receptacle having side members, and support means for the frame including a base in fixed position below the lay, an upright having the lower end thereof pivoted with respect to the basefor movement to front and rear posi-, tions, means normally holding the upright in rear position, and a carrier on the upright engaging said side members and supporting the frame and receptacle, said. upright being swingable to the forward position thereof and the side members being removable from the carrier by upward motion with respect to the upright.
